for rotating the same, It isunderstood that the door may be of anysuitable construction and the bearing .85 suitably located therein.\Vhilethe door is shown solid, it

may, for instance, be built up of laminated gear 91 fixed thereto,spaced from the rear plate by spacing collar90. (See Figs. 2, 3 and 8.)This spiral-gear meshes with a spiral-gear 92 fixed to a cross-shaft 93,

'joui'naled in bushings 9a, 95, fixed to the rear plate of the door inbearings 96, 97. The cross-shaft has a spiralrgear 101 fixed thereto,which meshes with 'a' spiral-gear 102, rotatable with a shaft 103,journaled in the rear plate 75 and in a bearing 104 of the door, asiaacing collar .105 being between the spiral-gear 102 and said rearplate. The construction is the same as that shown in Fig. 9 for rotatingthe upper locking-bar.

A gear 106' rotates with said stud and meshes with a'gear 107, forrotating a wormgear 108 shown as integral with said gear 107, androtatable on astud 109 fixed to the rear plate75, by means of a threadedshank 110 extendingfrom said stud andhaving a nut 111 receivedthereover, the construction being the same as that shown in Fig. 10.

for fixing the stud "7 1 in place: The end of said stud 109 is receivedin a bearing 112 in the door. The worm-gear 108 'meshe with the teeth ofthe bar 51.

v A block 115 is threaded to the cross-shaft on. a screw-rod portion 116of said crossshaft, and is; guided along the rear face of the door,having slide-connection with the rear plate 75 of the door, to preventrelative rotation between said block and the door, whereby said block ismoved axially on said cross-shaft. '(See Figs. 2, 3 and 8.)

Endwise movement of the shaft is prevented by contact between thespiral-gears thereon and the bearings of said shaft. Movement of theblock in one direction is limited by the bearing 96, and in the oppositedirectionby a bevel-gear-117 fixed to said. crossshaft, as by a pin 118,the bevel-gear serving as a stop-collar.

The endwise limits of movement of the block correspond to the limits ofrotation imparted to the rotatable locking-bars for locating thedividing plane between the barsections i'n the plane of the jointbetween the door and wall, at one limit of said movement, and locatingsaid bar-sections crosswise of said joint so that the parting planebetween said bar-sections is substantially at right angles to said jointat the other or locking limit of movement of the bars.

When at this latter limit of movement, the block is arranged to have anobstructingpart placed there-against to prevent re-. rotation of thebars in release direction, instanced asthe bolt 121 of. a suitablecombination lock 12.2, operable from the outside of the safe by a handle123 011 a suitable spindle 1241-, connecting the handle with the tumblermechanism of the locln This 0bstructingpart may take the form of anyther suitable obstructing mechanism or locking mechanism, as ofacombination lock, ortiine lock, or other suitable locking device.

. When the obstructing part is in obstructing rel" "ith the bar or barsrotated in their sockets with the door closed, the door is locked, andwhen the obstructing part is removed from obstructing relation with theblock the bar mechanism ma be 0 aerated to J 7 J 1 rotate the bars andunlock the door.

Wle pa 1 a l l e ba a1 u g +1 a bq 4 a b +1 employ er, tie same may ciota c y n16 handle 86 by continuing the operative mechaism to said.bars, instanced as accomp. seed by means of upright-shafts 125, 126,'ournaled in bearin s 127 128 fixed to the l b 7 rear plate so of thesafe-door, and having 'iinate ends, said bevel-gears meshing '1 thebevel-gear 117. Spirahgears 18 1, 185, are fix ;lto the respective endsof said shafts, and esli with spiral gears 136, 187.

The spii' gear 136 is fixed to a shaft 141 andhas a-spur-gear 142thereon, fixed to rotate therewith. (See Fig.9.) Theshaft isrotatable ina bearing 1 13 in the plate '75 and in a bearing 1 14 in the door. It isprovided with a flange 145 which, with the gear 14-2 and a washer 1&6,fixes the shaft endwise in a recess 14? between the plate 75 andthe'door. A spacing-collar 1 18 is located between the spiral-gear and'the plate. The construction of the shaft 103 and the parts mountedthereon is similar to the shaft 1&1 and the parts mounted thereon.

The spur-gear 142 meshes with a spurgear'151, which has a worm-gear 152thereon. These combined gears rotate on a stud 153, which has a reducedthreaded end 154; received through a hole in the plate 7 5. A nut 155 isthreaded over this reduced threaded end for clamping the stud to saidplate, the plate being located between the nut and a shoulder 156. Theforward end of the stud is located in a bearing 157 of the door. Theworm-wheel 152 meshes with the gear 71 on the locking-bar 52 forrotating the same.

'Siiniliar means, reversely placed, are provided for rotating thelocking-bar 53, indicated by similar but primed reference numerals;

I have GXQHIPllfiQCltllG means for rotating the locking-bars as mountedon the door,-although 1 do not limit myself to such location ofsaidrotating means, ass'aid rotating &

means may be mounted in the wall oi? the door-opening. and saidlockingdiars may be rotated 'lrom the outside of the same instead oftrom the inside of the same as exemplilied.

In operation. when the door is opein as illustrated in Fig. t. thesections ot' the locking-bar are respectively received in the wall ofthe door-opening and in the door. the parting planes of said sectionsbeing preferably coincident with the iaccs of the joints between thewall and the door.

Swinging the door into closed position and manipulating the handle 4:0,forces the door into the wall of the door-opening. and causes seating inthe joints of the same. and also causes the sections of the locking-barson the door to register with the sections ot the locking-bars in the*all of the dooropening. for coaetive relation between the mating facesof said sections.

hen now the handle 86 is turned, the worm wheels on the door. which meshwith the gears on the locking-bars. cause rotation of the locking-bars.the rotation of the sections oi? the locking-bars on the door be ingtransmitted by contact between the coaeting faces to the sections of thelockingbars in the wall of the door-opening, whereby the sections of thelocking-bars are arranged across the joints between the door and wallfor locking the door, as shown in Fig. 3.

During such locking movement, the block 115 has axial movement impartedthereto along the screw-portion 116, for forming a space between saidblock and the bearing 96. whereupon, by manipulation of the combinationlock, the belt 121 is moved into obstructing relation with said block,tor maintaining the bolt-works in locked relation.

Rotation of the bars beyond the desired angle of rotation is preventedby contact of the block 115 with the bearing 96. when the parting planesof the locking sections are coim-ident with the joints between the doorand wall tor unlocked relation of the door, the block 115 contacting thebcvclgcar ll'T when said bar-sections are located in the locked relationas shown in Fig. 3.

As an element of safety the spindle 833 is preferably a thin spindle.which would be severed if force were applied to the handle 86 torrotating the same in excess of that ordinarily employed for rotating thelocking-bars. in order to minimize or a void the danger oi burglariousrotation of said locki ng-ba rs.

My improved locking means is simple and ell'ective. and provides alocking bolt extending lengthwise throughout subshmtially the entirelength of the joint between the door and its wall.

In my improved device, further, the doorfaces of the joints are held inclose im- 'iingement againstthe wall-:liaces o'l said joints throughoutsaid joints, by substantial bars having close impingement with the wallsof the recesses in the door and wall in which said bars are located,:liorming uniting; faces of substantial area throughout substantiallythe lengths of said joints, and resisting movements of said door inburglarious attempts, by means of the pressure bar system or otherwise,for preventing the ilormation of suliicient space in the joints topermit introduction of explosive or other opening means.
